Read it through once

This man had plenty of clients--has plenty yet. He receives letters from spirits located in every part of the spirit world, and delivers them all over this country through the United States mail. These letters are filled with advice--advice from 'spirits' who don't know as much as a tadpole--and this advice is religiously followed by the receivers. One of these clients was a man whom the spirits (if one may thus plurally describe the ingenious Manchester) were teaching how to contrive an improved railway car-wheel. It is coarse employment for a spirit, but it is higher and wholesomer activity than talking for ever about 'how happy we are.'
